HORSE-POWER..

SPECIFICATION forming part of Letters Patent No, 259,379, dated June 13,1882.

Application filed April 11, 1852.

To all whom it may concern Be it known that I, WILLIAM O. FROST, of LeRoy, in the county of Genesee and State of New York, have inventedcertain new and useful Improvements in Horse-Powers, of which thefollowing is a specification.

My invention relates to that class of horsepowers shown in LettersPatent of the United States No. 240,480, granted April 19, 1881, toJabez T. Varren; and it consists in certain improvements upon themachine therein shown, which improvements will hereinafterl be fully setforth and claimed.

In the accompanying drawings, Figure l is a perspective view of myimproved machine; Fig. 2, a vertical section; Fig. 3, a plan view withthe top plate removed; Fig. 4, a view of the blocks for regulating theheight of the sweep; and Fig. 5, a detail view, showing a block on therest and the sweep in place.

The general organization of the machine is the same as that shown in thepatent to Warren above referred to. There is a drum or case, A, in whicha vertical shaft, A', rotates, imparting motion to the tumbling-shaft bysuitable gearing. Motion is given the shaft A by planet-wheels B, whichturn on bea-rin gs on the top plate, D, and gear with a pinion, a, onthe shaft. The top plate turns upon the upperend of the shaft A', and iscarried around by the sweep.

The object of the first part of my invention is to insure the perfectlubrication of the machine. The hubsOon theiop plate donotquite reach tothe bottom of the sockets in the planet wheels, and fit more orlessloosely therein, thus leaving oil-spaces. Oiling tubes or ducts o eX-tend from the top plate through the hubs C, so that oil maybe poureddirectlyinto the sockets of the planet-wheels. The hubs and the socketsof the wheels are chilled, and, as they overlowsfrom the sockets of theplanet-wheels lubricates the planet-wheels, the pinion a, the cogs inthe outside rim, the bearing ot' the shaft A', and the plate ordiaphragm E, on which the planet-wheels rest and move. Thus by supplyingoil to the sockets in the planetwheels in sufficient quantity themachine may be kept properly oiled. With this arrangement theplanet-wheel sockets can be readily The oil that' (No model.)

kept lled with oil, and there is little liability ofthe bearings runningdry. An extra oilingduct, o', is provided for oiling the bearing of thetop plate on the shaft A'. Two planetwheels are shown; but a greaternumber may be used, it' desired.

The next part of my invention relates to the means for varying theelevation of the sweep. The drawings show two sets of rests, F F and f fon the top plate for supporting two sweeps. However, the machine may bemade to work with three or four sweeps, in order to give greaterstrength and power, without departing from the principle of this partofmyinvention. In the organization shown in the drawings the employment oftwo sweeps is optional, and depends upon the work being done. In orderto support the sweepshorizoutally, or with theirv ends elevated, I makethe rests F and fhigher than the rests F f, and provide movable blocksor caps G, which t over the rests. This is illustrated more clearly inFig. 5, where the rest F is, say, twice as high as the rest F and thecap G equal in height to the rest F'. Thus, with the cap on the highrest the sweep will be elevated, and it'the cap be moved from the highrest to the low one the sweep will be sup- I ported horizontally, asshown in dotted lines. In order to afford the sweep a rm seat on the capand rest F', I bevel the edge of the rest and cap, as seen in Figs. 4and 5.

The next part of myinvention relates to the manner of holding orsecuring the sweep to the top plate,and,as incidental to this feature,the manner of adjusting the sweep endwise. The sweeps preferably rest insockets or between the brackets H,'of which the rests above describedform the bottom, and arev firmly held by loops or straps I, which areslipped under the open-bottomed or slotted sides of the brackets at h,the sweeps being iirmly clamped by cross-plates H and nuts t'. Thesestraps embrace the outer sides of the brackets, and serve to sustain andbrace them against the side strain'of the sweep. In order to givegreater strength and for convenience, other straps, J, held by hooks orsockets j on the top plate, are placed between the brackets and rests.By securing the sweep to the top plate by clamping devices it isunnecessary to impair its strength by making bolt-holes in it, as in theVroo patent of Warren above named. Any eudwise l sweep, and clampingdevices for securing the adjustment may be obtained by merely looseningthe nuts yi, shifting the sweep, and l[hen reclamping it in place. Inlight machines it will probably be sufficient to employ the centerstrap, J, only.

The several improvements above describedgreatly increase the value,strength, and eciency' of the machine.

Having described myinvcn tion, what I claim 1s- 1. The combination ofthe top plate, the planet-wheel having the central recess or socket, andthe hub on the top plate having the oil-duct through it, and on whichthe planetwheel turns, substantially as and for the purpose set forth.

2. The combination of the top plate, the sweep, the rests, and themovable cap which fits over the rests, substantially as and for thepurpose set forth.

3. The combination of the top plate, the sweep, the rests or sockets onthe plate for the sweep so as to permit its endwise adjustment,substantially as set forth.

4. The combination of the top plate, the sweep,the brackets which holdthe sweep,and the clamping straps or loops which embrace the outsides ofthe brackets and clamp the sweep in place, substantially as set forth.

5. In a horse-power, the combination of the top plate, the sweep, andclamping devices which bind the sweep to the plate, for the purpose setforth.

6. The combination of the top plate, the sweep, the rests or sockets forthe sweep, and a clamping-strap between the rests for securing the sweepin place, substantially as set forth.

In testimony whereof I have hereunto sub* scribed my name this 3d day ofApril, 1882.

WILLIAM O. FROST.
